Combine all ingredients except the toppings in a small glass jar. Cover with a lid or plastic wrap. Place in the refrigerator for at least 2 hours or overnight.
Uncover the next day and stir well. Top with some fruit or nuts.
Notes
Make sure you use a protein powder where you enjoy the taste.
Overnight oats can be stored in the fridge for up to 5 days so you can make a batch for the week.
You can adjust the sweetness level by adding or taking away honey in tablespoon increments.
If you want warm oats, heat in the microwave for 45-60 seconds, or until warmed through.
